Specification of Letters Patent.

Patented May 28;, 1918.

Application filed April 16, 1917. Serial No. 162,378

To all whom it may concern:

Be it known that I, LOUIS F. JURGENSON, a citizen of the United States, residing at Grand Rapids, in the county of Itasca, State of Minnesota, have invented certain new and useful Improvements in Paper-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to paper making machines.

The principal object of the invention is to improve the construction of the paper making machine shown in the Letters Pat- 6, 1910, and bearing the Serial No. 977,654.

A second important object ofthe invention is to provide a paper making machine using reciprocating suction boxes with means whereby any suction boxes may be independently removed and. replaced with out disturbing the .remainder of the boxes.

A third important object of the invention is the provision of improved means in a machine of this character whereby reciprocation of the boxes may be effected by certain links which have their major portions out of the path of removal of the boxes adjacent to the box to which the links are attached.

With the above and other objects in view, as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and specifically claimed. f

In the accompanying drawing, like characters of reference indicate like parts in the several views, and

Fig. 9 is a detail perspective view of a portion of the upper rail showing the reduced portion with the shoulders at the upper end which limit the movement vertically of the box carriers.

Fig. 10 is a plan of one end of a suction box with the screens removed.

Fig. 11 is a side elevation thereof.

Fig. 12 is an end elevation thereof.

Fig. 13 is a detail perspective view of one of the stools or supporting members.

Before proceeding with the detail description of the various parts of the invention it will be noticed that, as the connections on the line 66 of between the rotatable shaft and the opposite ends of the suction boxes are identical in every respect, reference will only be made to the connections between the rotatable shaft and the ends of the suction boxes on corresponding parts on the opposite side of the machine herein illustrated being designated by the 'same reference characters as those, parts which are referred to in detail.

It is also to be noted that of themachine which have directly. to do with the mounting of the boxes for their removal and replacement are illustrated herein, all other parts such as the screen on which the pulp is deposited and the like being omitted, as these parts do not vary only those parts from the usual and well known correspondlplg parts in the ordinary Fourdrinier mac me.

In the embodiment of the invention herein illustrated there has been disclosed a bottom frame havin a longitudinal member 10 on each side an atop frame having a similar longitudinal member 11. On the frame member 10 are secured brackets 12 which have offset flanges 13 at their upper ends for the purpose of securing thereto the member 11.

- Depending from the member 11 are spaced standards 14 the lower ends of which are reduced to provide shoulders 15 and slidable vertical on these standards are carrier plates 16 having notched ends 17 which engage ill the standards 14. These carrier plates are held in position by means of bolts 18, one side of the head oieach belt being cut away so as to bring the bolt close to the standard. These bolts 18 pass upward through bosses l9 and on the upper end of each bolt is a nut 20 whereby the bolt head and consequently the carrier plate 16 may be raised or lowered.

Beneath each of the standards 14 there is formed on the member 10 a stool 21 which is U-shaped in plan and carries cross rails 24 which extend across from one member 10 to the other. Moreover beneath the cross rails 24%, which are preferably made of "l"- shape are bolts 26 which are screwed upward through the member 10 so that the cross rails 2 can be raised or lowered by screwing up or down on the bolt 26.

The suction boxes are indicated in general at 27 and while it is not proposed to go into a detailed description of these boxes certain points may be mentioned. Each of these suction boxes is provided at each end with a projecting fian'ge 28 having a shouldered portion 29 on its under side, the shoulder being curved in a direction transversely of the box as can be seen by reference to Fig.- 10. Secured to each of these flanges is a plate 30 having at one end a boss 32 which forms the journal for a link bearing hereinafter to be described. Furthermore, each of the suction boxes is provided in the usual manner with a outed plunger 33 mounted on a stem 34: which projects through an opening 35 so that the position of the respective plunger 33 may be changed at will.

At 36 is indicated a shaft and on this shaft is mounted a pair of eccentrics 3T surrounded by straps 38. To one of these straps 38 is connected a pitman 39 which is journaled on the boss 32 of the box nearest the shaft 36. Also connecting this boss 32 with the third box in the set is a link 40 the cen tral portion or which is ofiset so that the second box in the set of boxes here shown at 4; can be removed without disturbing the linlr 40. To the other eccentric strap 38 is connected a link 41 which is ofiset in its cen tral portion and connects with the second box as best seen in Fig. l. in like manner the second box is connected with the fourth box by an offset linli t2 and it is to be observed that the link 41 is likewise ofiset to permit removal of the first box. it is obvione that while only tour of the boxes have been shown any number of boxes may be used, the odd numbers all being connected together by certain links as are shown at it) while the even numbers are connected by certan links as are shown at d2. Thus anyone o'r the boxes may be removed without disturbing the other boxes.

the removal of the boxes it is simply necessary to lower the plates 16 by proper manipulation of the nuts 20. lhen the cross rails 2a are brought up until they engage the bottom of the box whereupon the plates 16 may be lowered still further or the cross rails may be raised further until the bottom portion of the box rises above the plates 16 which support it. Under ordinary circumstances it will be noted that the shouldered portions 29 are between the plates and it is necessary to clear these shouldered portions a from the plates before the box can be moved laterally. However, after the box has been raised in the manner before described it may be readily pulled out laterally, it being merely necessary to disconnect the links whichare connected to that particular box. Furthermore by means of this construction it will be seen that the handles of the stems as which are shown at a3 are accessible at all times.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

it is obvious that many minor changes may be made in the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described but it is wished to include all such as properly come within the scope claimed.

Having thus described the invention, what 2. in a paper making machine the combination of suction box carriers, means for supporting said carriers for vertical movement, suction boxes on said carriers reciprocable longitudinally of the machine, means for reciprocating said boxes including linlts each connected to a box andcoffset vertically out of the path of an adjacent box, and means to receive andsupport said boxes with t io carriers in lowered position.

In a paper making machine, suction box carriers arranged in pairs, one carrier of each pair being at one side of the machine and the other carrier of said pair beingopposite thereto at the other side of said machine, a suction box having flanges at its ends resting on the respective carriers of. a

pair thereof, the lower part of said box being received between the pair of carriers to prevent movement of said box laterally of the machine, means to raise and lower the carriers, cross rails extending transversely of themachine and engageable beneath said box,

and means toraise and lower the cross rails.

6. In a paper making machine, suction box carriers arranged in pairs, one carrier of each pair being at one side of the machine and the other carrier of said pair being opposite thereto at the other side ofsaid machine, a suction box havlng flanges at its ends resting on the respective carriers of a pair thereof, the lower part of said box being received between the pair of carriers to prevent movement of said box laterally of the machine, means to. raise and lower the I carriers, cross railsextending transversely of the machine and engageable beneath said box, and means to reciprocate said box including links connected to said box and 011'- set vertically intermediate their ends to permit the passage of a second box.

In testimony whereof, I aflix my signature, in the presence oftwo witnesses.
